- Abstract:
- To improve real-time image matching and ranging accuracy in binocular vision ranging systems, this paper proposes a binocular distance measurement method, in which saliency detection and focal length fitting are combined. The method first corrects the distortion of the binocular camera and then fits the relationship between the camera focal length and object distance by using the characteristics of the binocular camera imaging and further applies the obtained image for saliency detection, and then the target object area is extracted. Finally, the surf operator is used to perform feature matching on the extracted region, and the matching point is substituted into the ranging model to obtain the distance of the target object. The results show that the saliency detection method can significantly improve the execution speed of the algorithm, and the focal length fitting can reduce the error of binocular ranging model, which significantly improves the binocular ranging system accuracy.
